qlcnic: info leak in qlcnic_dcb_peer_app_info() 



This function is called from dcbnl_build_peer_app().  The "info"
struct isn't initialized at all so we disclose 2 bytes of uninitialized
stack data.  We should clear it before passing it to the user.

Fixes: 48365e48 ('qlcnic: dcb: Add support for CEE Netlink interface.')
